g ef moun u pat 1 The upwa'idly projected partl'clei of Water 1 are fil st for a certain distance flylng n the hhamber 1 V direction of flow of the combustion gases, and after being reverted, fall in countercurrent to the combustion gases through the lower part of the tube 6, forming the upper part of the mixing chamber, into the compartment a, being kept by means of the screen 9 from entering the combustion chamher. A portion of the water particles projected upwardly, on touching the Walls of the tube 6, will unite, thus forming larger drops, which would flow down on the walls of the tube without mixing with the combustion gases. In order to avoid this, a cone-shaped guiding surface 1 is provided in the neighbourhood of the spray'nozzle k, which surface, by guiding the dripping water back toward the middle of the" tube compels it to take its way through the stream of the combustion gases; The warm water is led off from'the lower partof the mixing chamber a by a pipe m. y

Onthe waythrough the compartment (4 as well 'as'through the lower part of the mixing tube e and indirectly also by means of the screen 9, the combustion gases transfer a great part of their heat to the water, so that at their arrival in the passage around the nozzle In their temperature has fallen to about the same amount, at which inordinary cases they would escape without furtherutilization. "Bygthe direct contact with the cold water, which by means of the nozzle 7r, is very finely divided, their remaining utilizable I heat is drawn out of them, this'transmission of warmth being favourably influenced by the fact, that the upwardly flying particles of water are forming a resistance to the little drops falling,

down, so that a very intense contact of prolongated duration takes place in. the space above the nozzle. Of a most favorable influence for the utilization of the heat is furthermore the fact, that the water vapours, taken up by the combustion gases on their way through" the lower part of the mixing tube from the water, which there is already rather hot, are condensed again near the spray nozzle by the very finely divided particles of cold water, thus transferring their heat to the latter.

The higher the nozzle is is; placed i n.-,the tube 6, the lower the temperature of the combustion gases will be when escaping to the chimney. In order toenable regulating this final temperature and thereby also the draft of the chimney, the nozzle 70 maybe mounted adjustably, in the tube e, so that its position. as regards height can be varied.-' As shown" in Fig.2, the nozzle is carried I 1 V I 2 hemethod of heating;water,which comsi J causing hot combustion gases to flow upward through amixing 'cl1amberfl ,,having.;if-.

As is seen from what is said, by placing the nozzle in the upper part of the mixing chamber the advantages of the counter current principle are fully secured and at the same time also a suction effect is produced on the combustion gases by the water to be warmed. The influence of a change of the water pressure is practically eliminated, as the exchange of heat in the whole part of the mixing tube '0' under the nozzle 70 and in the chamber a is independent of the suction effect produced by the nozzle is. There is 7 warm water will have to pass beforebeing led olf. In order to facilitate'the cleaning of this filtering material, a "pipe 7 pro-,

videdwith a stop-cock 0, is insertedbetween, the water pipe 3' and thep'artof the water compartment underneath the filtering material. Opposite to it another pipe gis led from the part of the chamb-er'a above the filtering materialto the discharge pipe /12.

The cross-section of the opening, through which this pipe 9 discharges into the pipe m, and which opening-is disposed lower than the filtering mass, is smaller .than the.

cross-section of the cock 0 and ofthe pipe 7), so that part of the water enterlng through the latter will have to pass through the filter from below to its top, and carrying with it the impurities, will flow off through the pipe 9.

What I claim is:

1. The method of heating water which comprises causing hot combustion gases to flow upward through a mixing chamber have ing an elongated vertlcal portion of relative- 1y small crosssection and discharging the water to be heated into said vertical portion of the mixing chamber in an upwardly directed spray, permitting the water to fall in counter-current to the combustion gases through said vertical portion of the mix-ing chamber, and collecting and drawing off the heating water, whereby heat of the combus-' tion gases is transferred direct-lyto the water and water vapor 1s condensed out of partially cooled gases by the Water spray and the suction of the spray aids in the move-- J ment of the gases.
